Dylan Carlson's Earth helped define the drone doom aesthetic in the '90s, a genre indebted to minimalist composers as much as Black Sabbath. After a long hibernation, Carlson emerged with a new lineup and sound in 2005, with a studio album on the label Southern Lord - fitting considering Earth's direct influence on the label's Sunn 0))). In the aughts, Earth moved toward a cleaner, country-inflected guitar sound and continues that trajectory on this year's "Angels of Darkness, Demons of Light 2." With Fontanelle, Stembo.
